ABSTRACT:
A device for de-dusting, i.e., removing dust, from a particle flow in an enclosure. The device is optionally associated with a unit for dense loads which supplies the particle flow. The device is useful, for example, for removing dust from catalyst particle flows and from adsorbent particle flows. It is also useful for removing dust from grain or cereal particles, for example, being supplied to a silo.
